There is a thread here, which is interesting, and to which I'd like to add my opinion:

Aikido, and the whole world will be different. If I train well, and develop my Aikido, it will seem to be better. If I train less well, and devolve, it will seem worse, and I'll be looking back on the "good old days". There are some pretty tremendous younger teachers who will probably just get better. The good old days weren't all that good, and tommorrow aint as bad as it seems (to quote Billy Joel).

There is also a sub thread which is one of the most stupid and inane things I've read in a long time. I'm proud of ya fellas.
